The best thing you could do is to clearly explain the tree structure on how you would COMPLETELY like the AA to function. Is it that your looking for a auto attendant like a ACD? one with out any mailboxes? Are you trying to stop calls coming in from a back door number thru the AA to individuals desks? Believe me if its been thought of its been attempted. So please shoot straight on what you want. And as in any software defined program your only limited by your $$$.
